nginx配置基于IP的虚拟主机

Nginx支持多种类型的虚拟主机：基于IP的虚拟主机，基于域名的虚拟主机，基于端口的虚拟主机

增加两个IP别名

ifconfig ens33:1 192.168.86.135 broadcast 192.168.86.255 netmask 255.255.255.0 up
route add -host 192.168.86.135 dev ens33:1
ifconfig ens33:2 192.168.86.136 broadcast 192.168.86.255 netmask 255.255.255.0 up
route add -host 192.168.86.136 dev ens33:2

上面配置在服务器重启后会消失，可以将上面四条命令添加到/etc/rc.local文件中，让系统开机自动运行。
以下是我虚拟机ifconfig的显示：

路由表信息，可以使用netstat -rn或者Ip route（这种方式不利于查看）

[root@localhost conf]# route -n
Kernel IP routing table

在nginx的配置文件中，配置三个基于IP的虚拟主机，如下所示：

		# 第一个虚拟主机
        server {
                listen 192.168.86.134:80;
                server_name 192.168.86.134;
                access_log logs/134.access.log combined;
                location / {
                        root /root/hbk/server134;
                        index  index.html;
                }
        }

        # 第二个虚拟主机
        server {
                listen 192.168.86.135:80;
                server_name 192.168.86.135;
                access_log logs/135.access.log combined;
                location / {
                        root /root/hbk/server135;
                        index  index.html;
                }
        }
        # 第三个虚拟主机
        server {
                listen 192.168.86.136:80;
                server_name 192.168.86.136;
                access_log logs/136.access.log combined;
                location / {
                        root /root/hbk/server136;
                        index  index.html;
                }
        }

在/root/hbk目录下建立对应目录

[root@localhost hbk]#mkdir server13{4,5,6}
[root@localhost hbk]# cd server134/
[root@localhost server134]# echo "server134 huangbaokang" > index.html
[root@localhost server134]# echo "server135 huangbaokang" > ../server135/index.html
[root@localhost server134]# echo "server136 huangbaokang" > ../server136/index.html

重启nginx
